Product Category
Plug
Three-pole F-frame plug-in design enables fast busway integration and minimizes enclosure footprint. This translates into shorter installation times and tighter equipment layouts, which is crucial in crowded electrical rooms and retrofit projects. In practice, technicians can drop in the unit without rewiring extensive bus duct connections, accelerating commissioning on new lines. The 90A amperage rating provides balanced protection for feeders and motors, while the robust interrupt ratings—65 kAIC at 240 VAC, 25 kAIC at 480 VAC, and 18 kAIC at 600 VAC—deliver reliable fault protection across typical industrial loads, reducing nuisance trips and extending equipment life. Grounding options offer 50% integral or housing grounding, simplifying wiring schemes and improving fault path reliability during audits and inspections. The product’s ANSI, CSA, IEEE, and UL 857 certifications ensure regulatory compliance and safer installations. Busway compatibility and plug-in simplicity minimize field modifications, improving installation predictability and project ROI. A one-year warranty (or 18 months from shipment) further supports total cost of ownership and maintenance planning for industrial users.
